Issue with free surface, development version of ASPECT and deal.II 9.4.0/9.4.2

1

@sibiaoliu pointed out in the ASPECT forums ([link](https://community.geodynamics.org/t/problem-with-update-strain-rheology/3057/6)) that the continental extension cookbook crashes when run with a recent version of ASPECT (version 2.6.0-pre (master, 69faf2563)) and deal.II 9.4.2. The...

Poor nonlinear solver performance for VEP rheology + particles + continous compositional fields

4

While updating the continental extension bookmark (see attached PRM), I found that switching between using continuous and discontinuous compositional fields (`set Use discontinuous composition discretization =` `true` or `false`) in...

[WIP] Add prescribed dilation to visco plastic

1

Supersedes #3119, but is only open now for discussion and testing. @cedrict @tjhei @bobmyhill - The PR contains a working example (it runs). The code can be cleaned up quite...

[WIP] add python script for prefactor scaling

3

A python script to correctly convert viscous flow prefactor terms from experimental studies such that they are internally consistent with ASPECT's rheological conventions and assumptions. @bobmyhill @jdannberg @anne-glerum @cedrict -...

dealii build fails on Mac arm due to use of "unary_function"

3

While building deal.II via candi on recent arm-based mac (Sonoma 14.5), I ran into the following error while compiling deal.II 9.5.2 (i.e., it made it through installation of the other...

Solution divergence between different combinations of linear and nonlinear solver schemes

7

This post is a follow-up from a related series of issues and pull requests (#4370, #4563, #6002) that discuss solver failure or solution divergence for different combinations linear (`AMG`, `GMG`)...

Document default boundary condition for Stokes solve

1

[Per this post on the forum](https://community.geodynamics.org/t/boundary-velocity-flow-in-at-bottom-leads-to-a-failure-of-convergence/3627/4), it is not clear from the manual that if one does not specify a boundary conditions (velocity or traction) for a given boundary, it...

update continental extension cookbook

1

This PR updates the continental extension cookbook to use a number of features that improve the (1) performance (speed) and accuracy of the simulation and (2) make the PRM file...

[WIP] Add compressible EOS option to visco plastic material model

1

An initial step towards adding the option to use the `multicomponent_compressible` EOS in the visco_plastic material model. In theory no functionality has changed with the initial commit and the goal...
